1. A method programmed in a non-transitory memory of a device comprising: placing a first set of 3D patches of geometry on a first canvas; placing a second set of 3D patches of an attribute on a second canvas, wherein the first set of 3D patches of geometry are independent from the second set of 3D patches of the attribute; flexibly orienting the first set of 3D patches of geometry on the first canvas and the second set of 3D patches of the attribute on the second canvas; adjusting a first depth of the first set of 3D patches of geometry on the first canvas and a second depth of the second set of 3D patches of the attribute on the second canvas, wherein a delta of depth movement is compensated for by adding a luminous value to the delta; determining a safeguard distance between each patch of the first set of 3D patches of geometry on the first canvas, and determining the safeguard distance between each patch of the second set of 3D patches of the attribute on the second canvas; and implementing background filling of the first canvas and the second canvas.
